The advantages of employing metal in the construction of articles ofifurniture are well recognized, but the development of metal furniture has been hampered by'the high cost of producing such articles'as compared with like articles produced from wood, due,

ploy wherever possible sheet metal parts'in place of solidmetal parts in order to decrease production costs Another important object is the provision of a knock-down structure which may be readily assembled so that it may be shipped in knock-down form and the costs of shipment thereby minimized.

Other objects and advantages will be apparentfrom the following detailed description of one embodiment of the invention.

In the drawings, there is illustrated an armchair embodying my invention. The chair comprises, in general, a back member which constitutes the back and rear uprights, a back rest, a seat frame secured to the rear uprights and having. front leg members secured thereto,-l:"a seat member supported by said seat frame, and side. arms secured to the rear uprights at one endand-to the. seat frame at the other end. 1 j The backmember'l is preferably formed from steelftubing bentfito the form: shown which provides) uprights connected byf an a'rcuate upper cross member, the uprights extending downto formrear legs,as shown.

The back member so formed isbentoutwardly appe'aring'arcuate, in profile and givinga graceful rearward tilt thereto which is conducive to thecomfort of the occupant of the chair; The inner sides of. the arcuate cross member and the uprights are provided with openings to receive projections formed on the edges of a back rest2. "1 The back rest may be, as desired, upholstered,caned,or as illustrated, "of solid metal artistieally designed. Formed on theupper edge'of the backrest 2,'there are two verticaliprojec 'tions 3, and on each of theside edgesthere is a horizontal projection 4. Theback rest is assembled in the back by inserting th'e-verg tical projections 3 inthe openings provided therefor in the cross member, forcingthe up r'iehtsapart brin i horizontal p ojecf Fi jg is a section ,on line 2 2 o Fig. e I

frame 5 is secured'tov the "rear uprights" by means of bolts 6." The seatifr'am'ej 5 is desirably formed from solid metal be'ingchannel shape incross section as shown. I Indentations are formed at the rear corners to receive the rear uprights and at thispoint the metal ,of the outer flange 7 is increased to strengthen the seat frame at the point of support. At

the forward corners, upwardly inclined extensions 8 support the lower ends of the arms. On the lower surface of the seat frame 5, at the forward corners, integral downward extensions provide conical downwardly flaring sockets 9 the upper ends of which form inner stop shoulders. These sockets are adapted to receive with a snug telescopic wedging fit the upwardly tapering conical upper 'end .por-

tions'o'f tubular leg; members 10, which are shown as gradually tapering. downward from the sockets 9.

'The leg members 10 are preferably formed f shoulder against which the lower end of the leg abuts,sandfithe lower. hollow portion" of the foot 11 being provided with a wooden plug: 13 which rests onthe floor. The footll is placed over the'lower end of the leg '10 and the through bolt 12 inserted in the bore in the 7 solid central portion of thefoot 11 The upper end of the leg. is 'then inserted in the socket .9 in the seat frame and thebolt 12 entered in a theradedopening provided-therefor. v The bolt 12is then screwed into the seat frameand tightly clamps the leg member be tween the foot '11 and the seat frame 5. The lower hollow portion of the foot is then closed by. the woodeniplugla- V v.

w Arms: hich are adaptedtobe securedto the b'ac 7 atone end to the overhanging portion-8 ofithe seat frame at the other end, are

, preferably formed from solid metal having solidends l4and;15,- and an inverted channel shape portion 16 intermediate the solid ends.

On the surfaceof that end 14, which is adapted to beconnected to. the rearupright, there I is providedan overhanging tongue 17. The tongue comprises an upper rectangular portion substantially" the width of'the rear upright, the upper portion of which overhangs the upper edge ofthe arm, and a lower elon gated rectangular portion adapted to be received :ilil} a slot provided therefor and resist lateral forces-on the arms. Thus this tongue is ofsubstantially the shape of the capital letter TL The rear upright is provided with an opening having vthe same general outline as the aforementioned tongue, being of slightly less'l'ength, so that, whenthe tongue is re ceivedv within the opening the overhanging portionengags the inner surface of the tubular uprightjahove theopeningitherein. Also the lower narrower portion of this T-shapedtongue sat the same time snugly seat member 21.

received in the lower narrower portion of the T-shaped slot in the front wall of the tubular upright l, with the adjacent end of the arm fitting closely against the front face of this upright (Figs; 6 and 7), so that thereby a firm and rigid connection is made between this upper rear end 145 of the arm and' the tubular upright 1. Near the upper portion of the opening provided for the tongue the sides of the tubular upright ar'e undercut substantially the thickness of the metal so that at the point where the surface of the arm and the snrf ace of the upright meet they are coplanar and the curvature of the surface of the arm blends into the curvature of the surface of the upright. The lower end of the surface 14 is drilled and. threaded to receive a special screw 18 by means of which. it is'hel dl in contact with the surface o'f. the upright v The rear surface of the upright is drilled to receive the elongated head of the screwl8' the end of which is flush with the surface of the upright in the assembled position. The lower. end 15 of the arm isprovided with a socketv into which a projection 19 on the overhanging portion 8iof the seat frame 5 is received. The lug and socket are bored'centrally to receive a bolt 20 which is threaded into the drilled Opening in the arm and secures the end. .5- t fl at frame. The lug 19 is adapted to relieve the bolt 20 of the shearing stresses which accompany'lateral pressureon the arms.

,A metal laced seat member21 is bent at the edge thereof to formal flat depending and downwardly terminating flange 22 whichis adapted to be secured between upflanged flat clamping strips 23"to the inner fiatdepending and downwardly terminating flange 24- of the ch'annel-shaped seat frame The L seat clamps 23 are des rably formed-from hot rolled round edge steel-which is bent tothe desiredshape and diune-nsions. The flange 22 of the-seatmemberis firmly clampedbetween these strips which aresecured tot-he seat frame by bolts 25. Theclamping strips 1 '23 are continuous, as-shown in Fig; 4, i In efr fecting assembly the inner strip 23 maybe placed at the inner sideof the seat flange 22,

then the outer strip 231112 be pushed over the seat flange 22 from the side adjacent the Y1 Thereby there -will: be; formed; a unitary seat panel of which the clamping strips 23 will" form the frame. A

plurality of extensions 26, which are secured" by means of tap bolts, as shoWn','to: drilled 7557s and threaded lugs 27 formed on the lower surface of the seat frame '5 near the inner flange 24 thereof, extendinwardly at ari'ght angle to the edge of the flange 24 and'support the clamping strips together with the seat member. I V v y The above describedseat construction, as shown in the drawings, has a number of'manufacturing and other advantages, Alsothe particular construction shown maybe some therefor.

what modified in some instances, where thought desirable for various reasons,while still retaining the major advantages. It has been found very convenient in manufacturing and assembling to make up as a separate and independent unit the panel comprising-the metallic seat bottom 21 with its marginal flange 22 together withthe inner and outer clamping strips 23 which form a panel frame The construction shown in the drawings providesforthe-assembly of this unitary seat panel with the seat frame 5 by carrying out either oftwo slightly. different operations, according as may be found most convenient or desirable in any particular instance. I a

In one of these ways of effectingthecomplete assembly as shown in the drawings, the bolts 25 may be removed from or originally left out of the panel frame of the seat panel. Then, with the supporting lugs 26 projecting inwardly, beyond the lower edge portion of the seat frame flange 24, as shown in the draw ings, the seat panel unit may be pushed down from the upper side of the seat frame 5, with the outer seat panel framest'rip 23 fitting snugly within'the vertically flat surface of the inner seatframe flange 24, until the lower edges of the clamping strips 23 whichform the seat panel frame abut against these projecting lugs, 26. Then'the bolts 25 may be inserted and their nuts tightened, as shown in the drawings, thereby'not only preventing thepossibility of accidental disassembly but also firmly and securely clamping together the'inner clamping strip 23, the seat flange 22, the outer clampingstrip 23 and the seat frame flange 24,-thus providing in a .convenient manner a strong and secure assembly of all of these parts.

In ,the particular illustratedconstruction and asshown in Fig. 4;, it will be noted that a surrounding series of eighteenof the clamping and securing-bolts 25 are providedand also that a similar series of thirte'en of the supporting lugs '26 t are provided interspaced relation between the bolts 25 It may be further noted, as clearly indicated in Figs. 2 and 9 ofthedrawings, that thesesupporting lugs are notched,upwardly into the lower edge of the seat frame flange 24, thereby preventing the possibility of theselugs becoming accidentally rotatively displaced on their securing boltsby which they are both displaceably and removably attached: to the lugs 27, the lugs26 being thus securely held in their projecting supporting position both before and after the assembly or installation of theseat panelin the seat frame 5. v

In the construction shown in the drawings another way is provided by which the above noted assembly of the seat panel with the seat frame 5 may be effected, with the same final result. It will be noted, as shown in'Figs.

" 2 and 9, that the openings in the seat frame flange 24 for "the bolts 25 are slotted'downwardly through the lower' edge of this flange 24. Therefore, in the course of manufacture,

after the seat panel has been assembled with its clamping strips 23 in place, as hereinbefore described, the bolts 25 may be then placed in position on the seat panel frame, through the aligned apertures shown as provided in the seat flange 22 and clamping strips 23, with the nuts and lock-washers shown in the drawings in place upon these bolts, these nuts being either left loose upon the ends of. the

bolts or, if desired, for further security, they :may be tightened down against the outer clamping strip 23 of the seat panel frame. Also the securing bolts for the supporting lugs 26 'Inay be loosened or originally left loose, so that thereby these supporting lugs 26 maybe turned on thesebolts laterally aside position and, with the nuts on the outer ends of thebolts 25,.these bolts-may freely'pass into theslotted openings therefor in the seat frame flange 24:,- while theassembled seat panel frame is pushed int'othe'seat frame 5 with the outer clamping strip 23 in sn'ugengagement with the inner sideofthe seat frame yond the inner face of the flange 24. This outer clamping strip 23 thus enters the seat frame flange'2etfrorn its free edge, which is the loweredge in theupright or normal positlon of the iseveralparts'shown inFigs; 2 and 9 of-thedrawings; Then: the nuts on, the combined clamping and securing bolts 25 are tightened, asbefore, after which, or before,v it isimmaterial, the supporting lugs 26 are moved to their inwardly pro- 'jecting' position shown-in the drawings and their securing bolts are tightened the assembly of the seat panel with the seat frame-5 then being complete- I It is obvious that if desired, theslots shown in the lower edge portion of the seat frame flange 24 for the bolts 25 may be omitted and merely-bolt apertures corresponding tothe upper end portions of these slots then provided for these :bolts. ,Alsoit should be obvious that,forthe sake of further economy in manufacture,.and if so desired in any particular instance, the outer clamping strip 23 might be omitted andthe outer surface of the seat flange 22 then made to fit directly againstjthe seatframe flange '24 andhbe clampedagainst it by the bolts 25. Insuch a more simplified construction the inner clamping-strip 23 would b-yit'sel-f form a 7 panel frame for the seatmember 21'and the seat panel asa wholecould thus. be made up I of the seat panel, the clamping bolts 25 should be placed in position on the seat panel with their'nuts tightened down against the seat flange 22. Orinstead, if desired, or in addition to the bolts 25, the flange 22 ofthe metal seat bottom 21 maybe spot welded at intervals to the inner clamping strip 23, similar spot welding being commonly employed in the construction of various articles of metal furniture. However, the employment of the -twocla1np1ng strips 23 as shown in the drawingsprovides'a stronger and more secure preliminarily assembled seat panel, considered :asa unit prior-to its assembly with the seat frame 5.

.. The-assembly'of the armchair will be obvious from the above particular description.

-cured to the said upright, an arm having its rear upper end shaped to fit against the front face of the said upright, a T-shaped locking tongue projecting inwardly and upwardly from such end of the arm and pro- -videdat its upper end with an upwardly projecting overhanging portion, the front wall-of the said tubular upright beingprovided with a T-shaped slot with the upper of a seat member having a flatsurrounding depending downwardly terminating flange,

end of this slot terminating below the upper end of the said T-shaped tongue sothat thereby the'upwardly projecting overhanging end portion of the tonguewill have aninterlocking engagement with the inner side of the 'front'wall of the tubular upright'above the said slot therein with the said T -shaped tongue as a-whole projecting tothe inside of the tubular upright through such T-shaped slotand with the adjacent end vface of the arm abutting against the front face of the upright, and means for securing'the lower front end of the said arm to the said seat frame. o
